Packing three drivers into a “relatively small trapezoid enclosure,” its three-way triaxial configuration delivers enhanced output for its size and “gives it the edge over comparable two-way systems in terms of superior mid- and high-frequency performance.” Martin says adding a compact Martin Audio SX subwoofer to extend low-frequency output creates a dynamic, four-way set-up with a small footprint.

To ensure the most effective use of amplifier count, THS is designed to be bi-amplified, with an internal passive network performing the mid/high crossover function.

Martin says the THS triaxial driver’s LF section comprises a reflex-loaded, high-specification 15” LF driver with a 4” coil, waterproof cone and neodymium magnet structure. A 4” midrange ring radiator and a 2.5” HF ring radiator, both with high-temperature polymer diaphragms, are arranged coaxially at the rear of the LF driver and integrated into a 1.4” exit. This transitions through the magnet structure of the LF driver into an 85° x 50° horn. The horn itself is user-rotatable, with a large mouth to maintain pattern control down through the midrange.

The birch plywood enclosure is finished in hard-wearing textured paint and incorporates multiple threaded inserts to facilitate a variety of portrait and landscape mounting options—including eyebolt, yoke, pole and truss mounting. Twin handles assist installation and deployment, while a steel grille, with triple-layer polyester backing, protects the drivers and resists dust and water ingress.
